Military History of Korea During World War II - Korean Independence Movement

Korean Independence Movement

Main article: Korean independence movement See also: March 1st Movement and Provisional Government of the Republic of Korea

Upon Emperor Gojong's death, anti-Japanese rallies took place nationwide, most notably the March 1st Movement of 1919. A declaration of independence was read in Seoul. It is estimated that 2 million people took part in these rallies. The Japanese violently suppressed the protests: According to Korean records, 46,948 were arrested, 7,509 killed and 15,961 wounded; according to Japanese figures, 8,437 were arrested, 553 killed and 1,409 wounded. About 7,000 people were killed by Japanese police and soldiers during the 12 months of demonstrations.

After suppression of the uprising, some aspects of Japanese rule considered most objectionable to Koreans were removed. The military police were replaced by a civilian force, and freedom of the press was permitted to a limited extent. Two of the three major Korean daily newspapers, the Dong-a Ilbo and the Chosun Ilbo, were established in 1920.

Objection to Japanese rule over Korea continued, and the March 1st Movement was a catalyst for the establishment of the Provisional Government of the Republic of Korea by Korean émigrés in Shanghai on 13 April 1919. The modern South Korean government considers this Provisional Government of the Republic of Korea the de jure representation of the Korean people throughout the period of Japanese rule.

The Japanese occupation of Korea after annexation was largely uncontested militarily by the smaller, poorly armed, and poorly trained Korean army. Many former soldiers and other volunteers left the Korean peninsula for Manchuria and Primorsky Krai in Russia. Koreans in Manchuria formed resistance groups known as Dongnipgun (Liberation Army), which traveled across the Korean-Chinese border, using guerrilla warfare tactics against Japanese forces. The Japanese invasion of Manchuria in 1932 and subsequent Pacification of Manchukuo deprived many of these groups of their bases of operation and supplies. Many were forced to either flee to China, or to join the Red Army-backed forces in eastern Russia. One of the guerrilla groups was led by the future leader of communist North Korea, Kim Il-Sung, in Japanese controlled Manchuria. Kim Il-Sung’s time as a guerrilla leader was formative upon his political ideology once he came to power.

Within Korea itself, anti-Japanese rallies continued on occasion. Most notably, the Gwangju Students Anti-Japanese Movement on 3 November 1929 led to the strengthening of Japanese military rule in 1931, after which freedom of the press and freedom of expression were curbed. Many witnesses, including Catholic priests, reported that Japanese authorities dealt with insurgency severely. When villagers were suspected of hiding rebels, entire village populations are said to have been herded into public buildings (especially churches) and massacred when the buildings were set on fire. In the village of Jeam-ni, Hwaseong, for example, a group of 29 people were gathered inside a church which was then set afire. Such events deepened the hostility of many Korean civilians towards the Japanese government.

On 9 December 1941, shortly after the attack on Pearl Harbor, the Provisional Government of the Republic of Korea, under the presidency of Kim Gu, declared war on Japan and Nazi Germany. The Korean Provisional Government banded together various Korean resistance guerilla groups such as the Korean Liberation Army, which was involved in combat on behalf of the Allies in various campaigns in China and parts of South East Asia. Tens of thousands of Koreans volunteered for the National Revolutionary Army and the People's Liberation Army. The communist-backed Korean Volunteer Army (KVA, 조선의용군, 朝鮮義勇軍) was established in Yenan, China, outside of the Provisional Government's control, from a core of 1,000 deserters from the Imperial Japanese Army. After the Manchurian Strategic Offensive Operation, the KVA entered Manchuria, where it recruited from the ethnic Korean population and eventually became the Korean People's Army of the Democratic People's Republic of Korea.
